(3 brick sleeve 225mm x 225mm) Sleeve attachments to provide ventilation to specific areas.


A range of straight sleeves to accommodate one, two or three cavibricks. (High throughput cavibricks are designed to be used singularly or can be locked together to form larger brick-sized ventilating units.) When connected to a cavibrick the combined length is sufficient to accommodate all popular cavity wall widths. The three standard straight sleeves are: 75mm x 225mm, 150mm x 225mm and 225mm x 225mm. We recommend sleeves are protected with a cavitray where they pass through the cavity, to comply with NHBC/best practice. (See Sleeve and Duct Cavitrays.)
